Sterile bladder irrigator

Abstract

The invention provides a sterile bladder irrigator, which comprises a medical three-way valve, a urethral catheter, a liquid conveying tube and a drainage tube, wherein the urethral catheter, the liquid conveying tube and the drainage tube are connected with three connectors of the three-way valve; one connector of the three-way valve is an outer conical joint; the other two connectors of the three-way valve are inner conical connectors; the urethral catheter, the liquid conveying tube and the drainage tube are connected with the three connectors of the three-way valve through being tightly screwed via screw caps; the liquid conveying tube is used for feeding a flushing solution into the three-way valve from a liquid conveying bottle; the urethral catheter is used for feeding the flushing solution from the three-way valve into the bladder of a human body or guiding liquid in the bladder out of the human body; and the drainage tube is used for discharging out the solution from the urethral catheter. The urethral catheter, the liquid conveying tube and the drainage tube are connected with three connectors of the three-way valve through being tightly screwed via the screw caps, so that good sealing performance is guaranteed; in the whole operation process, the solution is not in contact with outside; the sterile operation is realized; the cleanness of the flushing solution is guaranteed; no fungal infection risk exists; and the use is safe and reliable.

Description

technical field [0001] The invention relates to a medical tool, in particular to a sterile bladder irrigator. Background technique [0002] Clinically, it has become a routine treatment to perform bladder irrigation for patients with continuous catheterization to prevent urinary tract infection. The conventional bladder irrigation method is to use a syringe to inject the solution into the urinary catheter, pour the solution into the bladder through the catheter, and then use the siphon principle to drain the injected liquid to achieve the effect of bladder irrigation. [0003] The existing bladder flushing method is to send the solution into the bladder through a urinary catheter, and after staying for a period of time, disconnect the infusion tube for delivering the solution from the urinary catheter, connect the urinary catheter with a drainage tube or a urine bag, and release the solution It is exported for the purpose of flushing the bladder, but the connection between ...
